Recently, public displays are often provided with tangible interfaces. Especially in the context of public visualization, tangible interaction modalities offer possibilities to actively engage a passer-by, which may lead to more information discovery. In this paper, we report on a comparative study that explores this hypothesis. We present a novel public visualization that deploys different forms of tangible interaction in combination with a public display in order to communicate civic data to a wide audience. In a deployment-based study in the urban context, we compared three tangible interaction modalities in terms of types of engagement and insight generation. We report on our findings and discuss a number of design recommendations for tangible interaction on public information displays.
